ISSUE & TIP

A surging sensation above 1500 RPM on a 1985 Mazda 626 may be caused by broken air injection reed valves. The broken reed valves allow exhaust to enter the carburetor through the air filter housing, rather than injecting fresh air into the exhaust system as intended. These symptoms can be easily mistaken for a carburetor or feedback circuit problem,
